Definitions
- the present invention relates to a dry powder inhaler.
- Inhalers are well known in the state of the art. There are different kinds.
- a first type of inhaler contains a reservoir receiving a multitude of doses of powder, the inhaler being provided with dosing means allowing each actuation to separate a dose of this powder from the reservoir to bring it into an expulsion conduit to to be distributed to the user.
- Another type of inhaler consists in arranging the doses of powder in pre-dosed individual reservoirs and then opening one of these reservoirs each time the inhaler is actuated. This implementation ensures a better seal of the powder, since each dose is open at the time of its expulsion.
- various variants have already been proposed, such as an elongated blister strip or blisters arranged on a rotating circular disk.
- the device to evacuate the empty capsule, the device must generally be disassembled, which exposes the interior of the device to any external pollution, may subsequently be transmitted to the user during a future inhalation.
- the bodies of these capsule inhalers are generally transparent to allow the user to see the interior of the dispersion chamber, and thus know firstly that the dose of powder has been dispensed after use, and on the other hand to check if the empty capsule has been evacuated.
- a transparent body generates certain specific disadvantages.
- a small amount of powder remains generally adhered to the walls of the dispersion chamber.
- WO2010 / 062744 discloses a container containing photosensitive compounds, the container having an inner body in contact with the photosensitive compounds and an outer body provided with a window of anti-UV material.

- the inhaler 100 comprises a hollow body 1 and having an upper opening and a lower opening.
- the upper opening is at least partially closed by a plate portion 120 fixed to said body and the lower opening is closed by a closure element, such as a hatch 150, pivotally mounted on said body 1 10.
- a closure element such as a hatch 150
- the plate portion 120 comprises guide means, such as rails 129, cooperating with projections 149 of the sliding member 140, to guide the translational movement of said sliding member.
- a pivoting cover 130 is assembled above said plate portion 120.
- This cover 130 includes the dispensing orifice 131, preferably formed at a mouthpiece around which the user will place his mouth to inhale.
- the device according to this first embodiment consists of five main parts, namely the body 1 10, the plate part 120, the sliding member 140, the cover 130 and the hatch 150. All these elements are assembled on each other by means of an axis 160 passing through a lateral opening 1 15 provided in the body 1 10, through appropriate lateral openings 135 of the hood 130 and through a hollow cylinder 155 formed in a portion of the hatch 150.
- At least one toothed element 161, 162 is mounted on said axis 160 to cooperate with at least one toothing 145 provided on the sliding member 140.
- a suitable fastening member 163 may be provided for releasably securing said axis 160 to said body 1 10 by assembling the different constituent parts together.
- the axis 160 preferably has a particular section, for example substantially square, and the toothed elements also comprise a similar section so that they are integral in rotation with the axis 160.
- hood 130 also includes openings 135 of similar shape so that the cover, the toothed elements and said axis 160 are integral in rotation.
- the plate portion 120 comprises a loading opening 121, advantageously provided with at least one, preferably three positioning ribs 125, advantageously evenly distributed around said loading opening 121. These ribs make it possible to position and hold tightly a capsule 10 in the desired position.
- the capsules 10 comprise an upper part 1 1 and a lower part 12 separable from said upper part, said ribs 125 serve to maintain said upper part 1 1 before and during the separation of said lower part 12.
- this part plate 120 also advantageously comprises a reservoir zone 122 formed by an area provided with a plurality of holes 123 for disposing one or more reserve capsule (s).
- FIG. 2 to 8 illustrate an operating cycle of the device according to this first embodiment.
- FIG. 2 which shows the device in the closed position before the first use, it is found that the body 1 10 forms inside a dispersion chamber 1 1 1 which will be intended to receive the powder after opening the capsule 10.
- FIG. 3 shows the device after opening the cover 130. It can be seen that the opening of the cover 130 causes rotation of the axis 160 due to the cooperation of the approximately square shape of this axis 160 with the correspondingly shaped orifices. 135. This rotation of the axis 160 thus also causes a rotation of the toothed elements 161 and 162 which rotate with said axis 160. A rotation of these toothed elements 161, 162 causes a lateral translation of the sliding member 140.
- FIG. 3 also shows a capsule 10 placed inside the loading opening 121. It can be seen that the upper part 1 1 of the capsule is tightly held in the ribs 125 provided in said loading opening 121. Furthermore, the lower part 12 of the capsule passes through a first opening 141 made in said sliding member 140 and which, in the open position of the cover 130, is opposite said loading opening 121.
- FIGS. 4 to 6 illustrate the closing phase of the cover 130 after loading the capsule 10.
- the hatch 150 will also close and the sliding member 140 will be brought to the left in the figures by the cooperation between the toothed elements 161 and 162 and the teeth of said sliding member 140.
- the lower portion 12 of the capsule 10 passing through the first opening 141 of said sliding member 140 a lateral displacement of this sliding member will break the lower portion 12 of the capsule 10 as illustrated in FIG. 4.
- the sliding member 140 acts therefore as a capsule opening means.
- the upper part 1 1 of the capsule 10 is of course maintained tightly in the loading opening 121, in particular by the ribs 125.
- Figure 7 illustrates the inhalation phase.
- the user places his mouth around the dispensing orifice 131 of the cover 130 and sucks in the direction of the arrow B, shown in FIG. 7. In doing so, he creates a stream of air inside. of the dispersion chamber 1 1 1 which will swirl the two parts of the capsules 1 1 and 12 inside said dispersion chamber 1 1 1.
- This swirling illustrated by the arrow C in Figure 7 will allow a total emptying of said capsule parts but also a good dispersion of the powder, and in particular a deagglomeration of any clumps of powder that may have formed.
- additional air intakes can be provided in the dispersion chamber to promote swirling of the inhalation stream.
- the cover 130 advantageously comprises a grid 137 through which the powder will be able to pass and be expelled in the direction of the dispensing orifice 131.
- the grid prevents the capsule parts 11, 12 from being expelled from the dispersion chamber.
- the user then inhales the dose of powder that was initially contained in the capsule 10.
- said dispersion chamber may have a frustoconical shape narrowing towards the dispensing orifice 131, in particular to accelerate the inhalation flow by direction of said orifice.
- the user opens the cover 130 again, which, as before, will tilt the hatch 150 at the end of opening.
- This tilting of the hatch 150 illustrated in FIG. 8 will make it possible to evacuate the two parts of empty capsules 11 and 12 from the dispersion chamber 11 1.
- the device is ready for next use.
- the user can close the device and wait to reopen it the next time he needs it.
- the user is not obliged to empty empty capsule parts after each inhalation but it can of course only do when the next opening of the device when it wants to load a new capsule.
- the hatch 150 may include one or more pins (s) 156 which snaps (s) slightly into the bottom of the body 1 10 in the closed position, to ensure a secure closure and reliable hatch 150 in the closed position.
- Figures 1 1 and 12 show openings 1 16 formed in the bottom of the body 1 10 through which said detent lugs 156 of the hatch will be able to pass.
- this snap is not too strong not to hinder the opening of the hatch when the user opens the hood 130.
- Figures 9 and 10 show perspective views of the device in closed and open positions
- Figures 1 1 and 12 are views similar to Figures 9 and 10 but partially cut away, showing the internal structure of the device in these two positions.
- the device is therefore particularly simple and clever. It consists of a small number of parts, so it is inexpensive to manufacture and assemble. Moreover, the presence of a dispersion chamber and parts of empty capsules that swirl allow to disagglomerate the powder and thus ensure a better distribution thereof to the user during inhalation. Finally, the evacuation of empty capsule parts does not require disassembly of the device which limits the risk of pollution thereof. The lack of disassembly of the device also avoids the risk of not being able to reassemble it, or to misplace the disassembled parts, especially in children or elderly people.
- the manipulation of the device does not require manipulating the portion forming the mouthpiece around the dispensing orifice 131.
- the risk of contamination at the dispensing orifice 131 is therefore also limited.
- the method of use of the device is very simple, the user having to move the cover between its two end positions to fully operate the device. Thus, he first opens the hood, then he inserts a capsule, he closes the hood and inhales.
- FIG. 13 illustrates in particular an exploded perspective view of the device.
- the inhaler 200 consists of only three pieces.
- a body 210 of substantially cylindrical shape is provided on its periphery with a mouthpiece 230 defining the dispensing orifice and a loading opening 220 adapted to receive a capsule 10.
- This body 210 may comprise a longitudinal central axis.
- the inside of the cylinder 210 forms a dispersion chamber 21 1.
- a first axial end portion of said body 210 is formed by a first gripping portion 270, fixed relative to the body 210. This first gripping portion could be simply formed by an axial edge of said body.
- this first gripping portion 270 has a particular external profile, to encourage the user to manipulate the device through it.
- This first gripping portion 270 includes a closure wall 271 of the dispersion chamber 21 1, said closure wall 271 having an opening 275, extending for example at an angle of about 60 ° to 90 ° in said wall of closure 271.
- the body 210 is open, and this opening is closed by a second gripping portion 260 rotatably mounted relative to said body 210.
- This second gripping portion 260 thus forms the second axial end portion of the body.
- this second gripping portion 260 has an external profile similar to that of the first gripping portion 270.
- each gripping portion 260, 270 with a respective hand, and rotate the one relative to the other to manipulate the device.
- a closure element such as a hatch member 250, also having an axial wall 251 provided with a window 255 whose dimensions correspond approximately to the window 275 made in the closure wall 271 of the body 210.
- This hatch member 250 is mounted to rotate integrally on a central axis 261 connected to said second gripping portion 260.
- ribs 263 formed on the end 262 of the central axis 261 cooperate with grooves 257 of said hatch member 250, as shown in Figure 13.
- the hatch member 250 is integral in rotation with the second gripping portion 260 of the device.
- the hatch member 250 is disposed within the body 210 to cooperate with the closure wall 271 thereof.
- the user grasps with both hands the two gripping portions 260 and 270 and rotate relative to each other, as will be explained in more detail below. At no time is the user required to touch the mouthpiece portion 230 to use the device.
- FIGS. 14a, 15a and 16a illustrate a capsule loading and opening phase 10.
- a cross section is seen through the body 210 and thus the dispersion chamber is visible.
- 21 1 the loading opening 220 and the mouthpiece 230, with in the center the central axis 261 which is rotatably mounted in said dispersion chamber 21 1.
- the user loads a capsule 10 according to the arrow A in the loading opening 220.
- the depth of said orifice 220 is adjusted so that when the user fully inserts the capsule 10 into said loading opening 220, the upper part 1 1 of the capsule is held tight in said loading opening 220 while the lower portion 12 of the capsule projects into the interior of the dispersion chamber 21 1.
- FIG. 13 the central axis 261 is provided with a projection 265, for example in the form of a tongue.
- said projection 265 will come into contact with the lower portion 12 of the capsule.
- Figure 15a shows the position just before the capsule is opened while Figure 16a shows the capsule being opened, with the projection 265 which pushes on the lower part 12 of the capsule.
- FIG 17 illustrates the position of the open capsule 10 with the upper part 1 1 stuck in the loading opening 220 and the lower part 12 which has fallen freely into the dispersion chamber 21 1 to empty into it .
- the Projection 265 therefore acts as capsule opening means.
- Figures 14b, 15b and 16b illustrate what happens at the first axial end portion of the body, and in particular at the closure wall 271 of the dispersion chamber.
- FIG. 15b shows that just before the capsule begins to open, there is still a small open passage but that as soon as the capsule is deformed, which is shown in Figure 16b, the opening is completely closed and the interior of the dispersion chamber 21 1 is closed.
- the capsule breaks and the powder empties into the dispersion chamber 21 1, it is closed at its axial end walls.
- the user can then inhale as illustrated by the arrow B in Figure 18. To do this, he places his mouth around the mouthpiece and will create an inhalation flow that will allow him to inhale the powder contained in the dispersion chamber 21 1 through the dispensing orifice 231.
- the substantially annular shape of the dispersion chamber 21 1 about the central axis 261 is advantageous in that it promotes the swirling of the inhalation flow from the mouthpiece.
- the mouthpiece preferably has a gate 237 to allow the powder to pass but prevent the capsule portions from being expelled into the mouth of the user.
- the user-created inhalation flow will swirl the lower capsule portion 12 which freely rotates within the dispersion chamber.
- the central axis 261 has openings 269, for example disposed around the projection 265. This is illustrated in Figure 13, but other openings 269 could also be provided along the axis 261. These openings have a double effect. On the one hand, they allow additional air intake during inhalation and thus still create different flows that further promote the emptying of the capsule, the swirling and deagglomeration of the powder. On the other hand, the holes disposed near the projection 265 ensure that the lower portion 12 of the capsule does not fit on said projection 265 by trapping powder. As soon as the user is going to inhale, the flow of air that will pass through said orifices 269 will expel said portion of capsule in the event that it is nested on said projection 265.
- the user After inhalation, the user preferably returns the device to its starting position by rotating the second gripping portion 260 in the opposite direction to the body. In doing so, it will open again the window 275 of the axial closure wall 271, and thus allow the evacuation of the lower portion 12 of the capsule through the aligned windows 255 and 275.
- the user comes to load the next capsule 10 in the loading opening 220, as illustrated in Figure 20, it will push the upper part 1 1 of the previous capsule, which was stuck in the loading opening 220, inside the chamber of dispersion 21 1. This can then also be evacuated out of the dispersion chamber. This is illustrated in Figures 21 and 22.
- the body 210 includes a window 219 and the hatch member 250 includes an indication 259, for example the word EJECT, which is displayed in said window 219 when the two windows 255, 275 are opposite each other.
- the word INHALE or the like can be displayed in the window 219 to indicate to the user that he is in the position in which he can inhale.
- Visual cues may also be provided on the second gripping portion 260 and / or the body 210, to visually indicate to the user the two end positions of said second gripping portion with respect to said body.
- This second embodiment therefore makes it possible to produce a device in which the user does not need to manipulate the mouthpiece to use the device. In addition, it does not need to disassemble the device to expel or evacuate the empty capsule parts after each use. The risks of contamination and pollution are therefore greatly limited, as well as the risk of loss of parts removed or those of not being able to reassemble the device after disassembly.
- This second embodiment is even simpler than the first, since it comprises only three parts. It makes it possible to ensure good dispersion of the powder, on the one hand by deagglomerating it in an appropriate manner by virtue of the capsule portion which swirls in the dispersion chamber, but also by virtue of the additional air inlets provided in the body 210 and / or the central axis 261.
- the method of using the device is also very simple, the user having to move the second gripping portion between its two end positions to fully operate the device. Thus, it first inserts a capsule, then it rotates the second gripping portion to its second end position, it inhale, and he returns the second grip portion to its first end position.
- the part of the body which forms at least one wall of the dispersion chamber is made of a tinted transparent material.
- This tinted material is adapted firstly to at least partially filter the ultraviolet rays, to prevent any degradation or deterioration of the powder contained in said chamber. This applies to the powder contained in the dispersion chamber before each inhalation, but also to powder residues that remain attached to or bonded to the wall of the dispersion chamber after each inhalation, and which are likely to be at least partially inhaled during subsequent inhalations.
- the use of a tinted transparent material allows a partial visibility of the interior of the dispersion chamber.
- the tinted character could be technically characterized by the absorbance coefficient.
- This absorbance coefficient is a unitless quantity which represents the ratio between the incident flux and the flux transmitted by the material.
- an anti-UV material will have a good absorbance coefficient in the ultraviolet wavelength range, namely between about 10 nm and 400 nm.
- Pigments may be added to the material to favor its characteristics, especially anti-UV.
- These pigments comprise chemical groups called chromophores which absorb ultraviolet rays, for example one or more of the following elements: Ethene, 1-Hexyne, Ethanal, Nitromethane, methyl bromide, methyl iodide.
- the chromophores are present in the pigments, which gives them a color. These are often carbon-carbon or oxygen double bonds, but there are other types. These groups are then incorporated in the matter. It is their percentage proportion which confers the desired color but also gives its different properties to the mixture.
- the material is advantageously a synthetic material such as for example COC (Cycio Olefin Copolymer) or COP (Cycio Olefin Polymer, PP (Polypropylene), SAN (Styrene Acrylonitrile) or, preferably, PCTA (Polycyclohexylenedimethylene Terephthalate). alloys of these materials together or with other suitable materials are also possible.
